Hi All I need a little help here. I have a TC with a HIPER ARC, several HIPER DSP cards, some Quad Digital cards and a Dual PRI-Card NAC. I have been running for a long time with the HIPER DSP cards without problems. I now need to run the Quad cards and can not seem to get the Dual PRI card to work(it did work at one time). The PRI line is coming from a Lucent Definity 3G switch and works fine with the Hiper DSP cards. When I connect the PRI line to the Dual PRI card all I get is a busy signal, the link does show that it is up and there are no alarms.. The Dual PRI card has the following configuration Framing Mode ds1esf Line Coding b8zs Response to remote loopback ignore Auto Busy disabled Dial In Address No Address Dial-in/Dial-out Signal WINK ACK WINK Enabled Dial in Trunk type E&M TYPE II The settings above are set similarly on the Hiper DSP card. Any help would appreciated. Thanks in advance LOU - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
